我已经在EditText小部件中添加了文本右侧的图像,使用以下XML:

<EditText
  android:id="@+id/txtsearch"
  ...
  android:layout_gravity="center_vertical"
  android:background="@layout/shape"
  android:hint="Enter place,city,state"
  android:drawableRight="@drawable/cross" />

但我想在单击嵌入图像时清除EditText。我该怎么做呢?

最好在编辑文本的右边有ImageButton,并给负布局边距与编辑文本重叠。在ImageButton上设置监听器并执行操作。

    final TextView mTvTitle = (TextView)findViewById(R.id.tvTitle1);

    mTvTitle.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;

            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(event.getRawX() <= (mTvTitle.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width()))  {
                    // your action here
                    Intent intent = new Intent(DeAddExpences.this,DeHomeActivity.class);
                    startActivity(intent);
                    return true;
                }
            }
            return true;
        }
    });

还有更优雅的方式: 不要在TextInputEditText中使用android:drawableRight或android:drawableEnd。

相反,你可以用:

<com.google.android.material.textfield.TextInputLayout
    ...
    app:endIconMode="custom"
    app:endIconDrawable="@drawable/..."

然后使用endIconOnClickListener:

textInputLayout.setEndIconOnClickListener {
  // Respond to end icon presses
}

我见过几个解决方案,但没有一个能说服我。要么非常复杂,要么太简单(不可重用)。

这是我目前最喜欢的方法:

mEditText.setOnTouchListener(
        new OnEditTextRightDrawableTouchListener(mEditText) {
          @Override
          public void OnDrawableClick() {
            // The right drawable was clicked. Your action goes here.
          }
        });

这是可重复使用的触摸监听器:

import android.graphics.drawable.Drawable;
import android.support.annotation.NonNull;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.EditText;

public abstract class OnEditTextRightDrawableTouchListener implements OnTouchListener {

  private final EditText mEditText;

  public OnEditTextRightDrawableTouchListener(@NonNull final EditText editText) {
    mEditText = editText;
  }

  @Override
  public boolean onTouch(View view, MotionEvent motionEvent) {
    if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
      final int DRAWABLE_RIGHT_POSITION = 2;
      final Drawable drawable = mEditText.getCompoundDrawables()[DRAWABLE_RIGHT_POSITION];
      if (drawable != null) {
        final float touchEventX = motionEvent.getX();
        final int touchAreaRight = mEditText.getRight();
        final int touchAreaLeft = touchAreaRight - drawable.getBounds().width();
        if (touchEventX >= touchAreaLeft && touchEventX <= touchAreaRight) {
          view.performClick();
          OnDrawableClick();
        }
        return true;
      }
    }
    return false;
  }

  public abstract void OnDrawableClick();
}

你可以在这里看到要点。

非常非常好,感谢所有参与讨论的人。因此,如果你不想处理扩展类带来的不便,你可以执行以下操作(仅为正确的可绘制对象实现)

this.keyword = (AutoCompleteTextView) findViewById(R.id.search);
this.keyword.setOnTouchListener(new RightDrawableOnTouchListener(keyword) {
        @Override
        public boolean onDrawableTouch(final MotionEvent event) {
            return onClickSearch(keyword,event);
        }
    });

private boolean onClickSearch(final View view, MotionEvent event) {
    // do something
    event.setAction(MotionEvent.ACTION_CANCEL);
    return false;
}

下面是基于@Mark的回答的基本侦听器实现

public abstract class RightDrawableOnTouchListener implements OnTouchListener {
    Drawable drawable;
    private int fuzz = 10;

    /**
     * @param keyword
     */
    public RightDrawableOnTouchListener(TextView view) {
        super();
        final Drawable[] drawables = view.getCompoundDrawables();
        if (drawables != null && drawables.length == 4)
            this.drawable = drawables[2];
    }

    /*
     * (non-Javadoc)
     * 
     * @see android.view.View.OnTouchListener#onTouch(android.view.View, android.view.MotionEvent)
     */
    @Override
    public boolean onTouch(final View v, final MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN && drawable != null) {
            final int x = (int) event.getX();
            final int y = (int) event.getY();
            final Rect bounds = drawable.getBounds();
            if (x >= (v.getRight() - bounds.width() - fuzz) && x <= (v.getRight() - v.getPaddingRight() + fuzz)
                    && y >= (v.getPaddingTop() - fuzz) && y <= (v.getHeight() - v.getPaddingBottom()) + fuzz) {
                return onDrawableTouch(event);
            }
        }
        return false;
    }

    public abstract boolean onDrawableTouch(final MotionEvent event);

}
